SPECIFICATION forming part of Letters Patent No. 446,230, dated February 10, 1891.

Application filed October 16,, 1890- Serial No. 368,348. (No model.) 7

To all whom it may concern: 1

Be it known that I, \VILL F.'HOYT, a citizen of the United States, residing at Dowagiac,in the county of Cass and State of Michigan, have invented certain new and useful Improvements in Grain-Drills; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the let.

ters of reference marked thereon, which form a part of this specification.

'is not in use or when transporting it from one field to another. This object is attained by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is an end elevation of my improved drill with one of the transporting-wheels removed, showing frame broken away. Fig. 2 is a perspective view of a portion of the drill embodying my improved features. Fig. 3 is a plan view of a portion of the machine. Fig. at is an enlarged perspective of the clampingplates detached, between which the spring pressure-rods of the shoe and covering-wheel are adapted to be secured. Fig. 5 is a perspective view of the scraper plate and cap,

adapted to be secured to the rear ends of the spring-pressure rods of the covering-wheels. Referring to the letters of reference, A indicates the transporting-wheels of the drill; 'B, the axle connecting said wheels; 0, the

' frame of the drill, and D the seed-box thereof, all of which parts are common.

E indicates the runners or shoes of the drill, to the forward end of which are riveted, as

shown at s in Figs. 1 and 2, the curved draftrods 11. Said rods curve upwardly and are slightly diverging, their upper ends being piv otally mounted on the trunnions c of the plates 1), secured to the under face of the front edge of the frame 0, as clearly shown in Figs. 1 and 2. i

F indicates the feed tube or hopper, secured at its lower end to the heel of the shoe E, as shown at s, and through which the grain is conveyed to the furrow in the ground formed by said shoe.

I indicates the spring pressure-rods of the shoe. Said rods are formed of one piece bent to aloop at their forward ends, as shown in Fig. 4, and extending rearwardly on each side of the hopper F. The rear ends thereof are. pivotally attached to the bifurcated end h of the arm 0, as shown in Fig. 2, the upper end of said arm being pivoted at r to the free or outer end of the swinging arm N, the opposite end of the arm N being permanently secured at a" to the rock-shaft K, which extends along the rear edge of the machine-frame, and which is actuated by the lever M,- attached thereto. The forward looped end of the rods I is secured between the clamping-plates P The ends of said bolt pass through theadja- 1 cent faces of the draft-rods H, and are firmly secured therein, as shown in Figs. 2 and 3, by which means the forward ends of the pressure-rods I are pivotally coupled to the draftrods. The lugs c of the plate P, extending between the draft-rods H, keep the upper ends of said rods spread and in contact with the trunnions c of' the supporting-plates Z). The plate P is also provided with the horizontal shoulders 12 on each side thereof, that are adapted to engage the upper edge of the rods H, for purposes hereinafter described.

J indicates the draft and spring pressure rods of the covering-wheels G, which curve upwardly at their forward ends and are secured between the plates T T, mounted on rods-and: covering,- wheels, and the spring may be securely clamped upon said rods, as-

shown in Fig. 2, thus firmly securing the plates T T to the rods 1, and the looped end of the rods J between said plates. The rods J extendrearwardly on each side of'the hopper F, and pass through and are secured in the hub 41 of the covering-wheel G. By this means said wheel is guided so as totravel directly in the furrow made by the shoe E in whichrtheseed is'deposited. The rodsJ extendslightly'rearwardof the wheel G, andare secured between the plates f f that are provided with the grooves 0 in their adjacent faces, that receivethe bent ends of said rods, as clearly shown in Fig. 5, saidplatesi being clamped upon-said rods by meansof thebolt a passing therethrough.

The under plate f is provided with a depending lip a, and: the parts are so-arranged that said-lip act-s as a scraper to free-the periphery, of the, wheel Gr from dirt during the operation of the machine, as shown in Figs. 1 and 2.

The shoes and hoppers,with: their draft- PI'GSSlll'BrTOdS and their actuating=arm O'and swinging arm N, attached to the rock-shaft K, are arranged consecutively throughoutthe machine-,asshown in Fig. 3, andiareadaptedto beoperated simultaneously-by means of the lever M, attached to-the-shaft'K-'., the grain beingconveyed to the'hopper F of the shoe fromthe seed-box Dby means of flexiblehoseaf. '(Shown by dotted lines in Fig. 1.) It

will. now be-apparent that by throwing: thelever lVLforwardtheshaft K is rotated, carry-- ingthe outer end of the-swinging arm N down-- ward, which, being. coupled to the arm 0,.

forces-said; arm down and depressestherear ends of the-spring-rods I-, coupled-to thebifur--' cated end 71. thereof, the shoulders-o of the plate-P, .to which the forward ends of the rods .1 arez-attached,,bearing upon: the edge ofthe rods'I-I. As the-rear endsof therods-I are depressed. the pressure thereon is conveyed through: the-rodsI to the shoeE. At the same timeithe rods I are depressed by theactiom abovedescribed, the forwardends of the-rods- J are carried down, throwing an: increased press-ure on t'hewheel-G,which position of thepressure-rods,- lever M,v and arm- N, is clearly shown by dotted linesin Fig. 1. By this arrangement it is evident that thepres-- sure; on the shoe and coveringwheel is spring-pressure,andmay be regulated as desired,.e1 1ab1inga heavy pressure to be applied when the? groundishard or a light pressure when itis soft and yielding.

The arrangementof transmittingthe pressure applied to the rods I' to the shoe E through the medium of theshoulders 2; of the plate P, bearing upon the draft-rods'I-I of said shoe, enables the shoe to drop into a depression in the surface in advance of the covering-wheel G, and prevents said wheel from raising the shoe from the ground when riding over an obstruction, thereby insuring a continuous furrow, which would not be the case were the connection rigid between the rods I and II.

--When it is desired to raise the shoes and covering-wheels in transporting the. machine f ro in one field to'another, the lever M' is thrown tothe rear, rotating the shaft K and raising the swinging arm N, thereby drawing upward on the arm 0 and raising the rods L'which engage with the annularfiange t at the upper end of the hopper F, raising said hopper-and shoe, as-sh'own in Fig; 2. The-rodsJ of the covering-wheel G beingsecuredtothe rods 1, said. wheel is also raised by the. sameoperation. Thus it willbe seenthat. by throwing theleverMF to'the rear the shoes and-covering-wheelsare simultaneouslyraised from the ground, and: by means of the-:segmentracl; L, that receivesthe locking-bolt h ofthe lever M, said lever may be secured. in. any. desired position. It will also. be seen that the-mannerof mountingthe-plates T T upon the-rods I permits of. their longitudinal adjustment thereon, and the forward ends ofthe rods J of the covering-wheel G being; secured b.e-'

that by sliding said plates rearwardly upon the rods I the forwardmovement of the lever M will throw a stilhgreaterpressure uponthe wheel Havingthus fully set forth. my invention, what I claim as. new, and desire tosecureby Letters Patent, is-

1'. In combination with the transportingwheels and frame, the hopper, shoe,-and-draftrods, thelatter having a pivotal connection with the frame,.theclamping-plates havinga .pivotalconnection with the draft-rods, the

spring-metal pressure-rods attached to said plates, said rods extending rearwardly of the hopper, the forkedarmcoupled to-said= rods,
